Note: In no circumstance should the secondary of the PT be shorted. The secondary of the PT should be grounded at one end. Please refer to the wiring diagram section for further details.

Current Input:Current Transformers (CTs) are required in most engineering applications. Typical

current rating for the secondary side of the CT shall be 5A (standard) or 1A (Optional), please refer to the ordering information appendix for further details. CTs must be used if the system rated current is over 5A. The accuracy of the CT should be better than 0.5% with rating over 3VA is recommended in order to preserve the meter's accuracy. The wire between CTs and the meter shall be as short as possible. The length of the wire have an effect on the accuracy.The wire size of current input is AWG15-10 or 1.5-2.5mm2.

Note: The secondary side of the CT should not be open circuit in any circumstance when the power is on. There should not be any fuse or switch in the CT loop. One end of the CT loop should be connected to the ground.

Vn Connection:Vn is the reference point of the Acuvim II series meter voltage input. Low wire

resistance helps improve the measurement accuracy. Different system wiring modes require different Vn connection methods. Please refer to the wiring diagram section for more details.

AcuRev1300 communication utilizes RS485 port, via Modbus-RTU protocol. The wiringterminals are A, B, S. "A" is called differential signal " ", "B" is called differentialsignal"-",

"S" is connected to the shielding of shielded twisted pair cable. The maximumdistance of Shielded Twisted Pair cable is 1200 m. The distance will be shorter if moredevices are on the

same communication link or using a higher baud rate.

If the master device does not have RS485 but RS232 port, a RS232/485 converter can beutilized. Typical RS485 network topologies include line, circle and star.

In order to improve communication quality, please pay attention to:

1. High-quality Shielded Twisted Pair cable is very important, AWG22 (0.6mm2) or lower isrecommended. Two cables should be different colors.

2. Pay attention to "single point earthing". It means there is only one point of the shieldingconnected to ground in a single communication link.

3. Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the network, evendamage the communication interface.

4. "T" type connection topology should be avoided. This means no new branches exceptfrom the starting point.

5.Keep communication cables away as much as possible from sources of electrical noise.When several devices are connected (daisy chain) to the same long communication line, ananti signalrefecting resistor (typical value 120- 300Ohm, 0.25W) is often used at the endof the circuit (the last meter of the chain) if the communication quality is distorted.

6. Use RS232/RS485 or USB/RS485 converter with optical isolated output and surge protection.

7. A infrared port is also available in the Display Module, which supports meterreading.

This chapter will introduce you about how to use some important functions, many advanced function could not be operated through single key, which also need communication interaction, thus we made PC tools software. This chapter would introduce some functions with the help of these tools.

Different specification of AcuRev 1300 series meters support different parameters, you’ll see the details in the function table. Take AcuRev 1304 for example.

4.1 Parameter settings

AcuRev 1300 series meters need basic settings so that the meters can work in the scheduled way. The figure below is the display of basic parameters that set by PC tools software.

Generally reactive:

2) Energy pulse output

Used to choose the pulse type that represented by the pulse outputted through P1,P2 terminals.

Active: P1,P2 terminals output pulse is active power pulse.

Reactive: the output pulse is reactive power pulse.

3) Demand

Demand supports 4 kinds of calculate methods, which is Sliding block method, fixed block method, rolling block and thermal demand method.

a) Sliding block method: set a 1-30min window time, that is calculate time of demand. The window slid once per minute, so does the demand value. In this method, in the operation state demand calculation method is displayed to slip.

b) Fixed block method: set 1-30min as a demand calculate cycle. The whole cycle just calculate the demand once. Which means the demand update time is equal to the demand calculate cycle. In this method, in the operation state demand calculation method is displayed to block.

c) Rolling block method: set 1-30min as a demand calculate cycle and 1 slip time. Demand cycle must be integrated multiples of slip time. Calculate 1 cycle’s demand at the end of the slip time. The demand update time is equal to the slip time. In this method, in the operation state demand calculation method is displayed to slip.

d) Thermal demand method: calculate the demand value through analog the theory

of the thermal demand table. Set 1-30min as a calculate cycle. In the whole cycle, we just need to calculate the demand once. Which means the demand update time is equal to the demand calculate cycle. In this method, in the operation state demand calculation method is displayed to block.

4) Sealing option

Choose the “meter clock + time of use”, the corresponding content(meter clock, TOU parameters, Daylight saving time parameters) can be sealed.(the change of corresponding time must proceed when the seal is open.)

5) Communication permission

Divided into low permission and high permission.

Low permission: important operation (like clear demand event record, programming event record, open cover event record, meter data, energy data initial energy data) disabled. But it can update to high permission through updating the communication permission.

High permission: The communication supports all functions. 30 min after updating to the high permission, the meter would lower its permission to low permission automatically, to keep the meter’s safety.

6) Display scan parameters

Users could add data to the display scan parameters through the PC tools software. The meter would cycling display the elected content.

According to the demand of users, we can depart the time to several sequence time segments. Each segment can point to the same or different rate (at most 4 kinds of rates ). The meter decides to which rate the current time should belong to according to its inner clock or communication command. To achieve TOU calculate, it should be calculated separated in different rate.

TOU energy time segment setting: at most 14 time blocks.Each block corresponds one segment table (at most 8 time segment tables). Each segment can point to anyone of the 4 rates.

User can use different time block, different time segment to fulfil personality demand. But to make sure the time is valid, the meter would examine the time setting strictly. If it is correct and has opened the TOU function, the meter would process the TOU calculate energy. If it is wrong and has opened the TOU function. The energy just cumulated to rate 1.

Time setting demands:

1. Number of time zone setting: after finishing the time zone number setting, the time zone would be divided according to the number of the time zone. Please attention that the time zone number should be integers from 1-14. And the time zone format should be open from small to large.

2. Time zone setting format: xx month-xx date, xx date time list. Only if the time zone be set according to the closed structure, it considered correct.

3. Date time segment meter's setting: The setting parameters of date time segment meter are interger from 1-14, after finishing the setting, the date time segment's parameters in the date time segment meter would be set in a increasing order according to the date time segment meter's setting.

4. Date time segment setting: the parameter should be integer from 1-14, after the setting finished, we can set the parameter in the date time segment table according to the set parameters.Only if the date time zone be set according to the closed structure, it considered correct.

5. Rate setting: the parameter should be integer from 1-4. It means the maximum that appeared in the TOU energy. After finishing the setting, it would be rate setting in the time

segment table. The rate parameter is one of 0,1,2,3(0:sharp; 1:peak; 2:valley; 3:even).

6. Holiday setting: the number of holiday is integer from 0-30, after finishing the setting, it would be holiday setting, which format is xx month-xx date.

Note: User can customarize the factory settings of time zone segment. When no asking, the meter would be set as the default factory settings. Users can recover the time zone segment setting value to the default value through communication.

The use of TOU energy holidays: in the TOU energy parameter setting part, firstly we should set the number of holidays, then set the demanded holiday in the holiday setting bar, the format is xx month- xx date. At this time, through setting the meter operate time, when the meter’s operation time is in the setting time, the energy would increase under the corresponding rate.

Note: time-division energy is with the highest priority on holidays, when the set of special date is valid, the measurement of energy would consider the holidays at first.

Weekly restfunction

The use of TOU energy weekly rest: weekly rest(bit0- Sunday; bit1-bit6: Monday- Saturday . when bit is 1, it means weekday, when bit is 0 , it means weekend.) through setting the clock, when the meter’s clock is under the weekly rest time segments, the energy would increase under the corresponding rate.

b)The value of the currentrate of self-communication order.

Daylight Saving Time function

Under the DST enable condition, if we choose fixed date option, it would change the DST according to the fixed date setting format. The format is month/date/hour/minute/adjust time(unit:min). if we choose unfixed date option, it would change the DST according to the unfixed date setting format.The format is month/ week/which week/hour/minute/

adjust time(unit: min), according to the above setting format, it would change the DST automatically.

Through this function, we can achieve the meter’s DST change automatically. When the clock operates to the DST start setting time, the meter could adjust the clock to some certain time segment in advance. But when the clock operate to the DST ending, the meter could adjust the time to some certain time segment pushed back.

4.8 Incorrect connection detection

AcuRev1300 series instrument has the function of connection detection, Can be set in the interface to the function that can, in the case of function can make can automatically detect instrument according to the instrument connection mode of connection is correct,its principle is as follows:

1. Lack of phase detection: a phase voltage value is 0, as lack of phase.

2. Voltage phase sequence detection: A phase voltage as the reference point, determine the voltage phase sequence, such as detected by reverse phase sequence, or could be N lines to meet the current and voltage and voltage is the voltage and the indirect inverse.To determine the voltage value, such as a two phase voltage values are with another phase voltage deviation is too large (0.3 times), was convicted for the phase voltage into the N wrong; Otherwise the sentence to indirect fault voltage, B, C phase fault.

3. Current detection: A phase voltage as the reference point, read the phase current and voltage between A phase Angle, to judge whether its value and standard value Φ Angle deviation within 30 °, if meet the requirements, convicted for the current connection correct; Between Φ +180° ±30°, jailed for current reverse; Other values for the current phase sequence error.

Visible, the calibration method is suitable for the situation that voltage current Angle should not exceed 30 ° (Each phase PF value should be greater than 0.866), and is based on A phase voltage reference direction, therefore should ensure that A phase voltage connection correct; As A phase voltage phase or connect with N, the current test results do not have reference meaning; Like the other two phase with A fault, the test result is correct, but may lead to inconsistent with system parameters.Such as the meter voltage wiring in order for B, C, A, wiring in the system in order for A, B, C, will cause A phase data does not match, need to pay attention to.

This chapter introduced how to use software to manipulate the meter through the communication interface.This chapter content master needs you with MODBUS protocol knowledge reserves and read through the content of all the other chapters in this manual, this product features and applications concept has a more comprehensive understanding.

The chapter’s contents include MODBUS protocol, communication format, application details of AcuRev 1300 series meter.

5.1 Modbus Protocol Introduction

1. Transmission mode

The mode of transmission defines the data structure within a frame and the rules used to transmit data.

Coding System 8 bit

Start bit 1 bit

Data bits 8 bit

Parity No parity / odd parity / even parity

Stop bit 1bit or 2bit

Error checking CRC

2. Frame

When data frame reaches the terminal unit, it goes through the unit via a special "port", theunit removes the data frame's header, reads the data, if there is no error, then it implements the data's task. Afterwards, the unit puts its own data with the acquired header, and sends back the frame to the sender. The response data frame contains: Address, Function, Data and CRC Check. Any error will cause a failure to respond.

2.1 Frame Format

Table 5-1 Data Frame Format

2.2 Address Field

The address field is at the start of the frame. It is composed of 1 byte (8 bits), its decimalvalue range is 0-247.

A master addresses a slave by placing the slave address in the address field of the

message. When the slave sends its response, it places its own address in this address fieldof the response to let the master know which slave is responding.

2.3 Function Field

When a message is sent from a master to a slave device the function code field tells theslave what kind of action to perform.

Table 5-2 Function Code

2.4 Data Field

Data field contains the data that terminals need to complete the request and the

data that terminals respond to the request. This data may be a numerical value, address or setting. For example, Function Code tells the terminal to read one register, Data Field needs to specify reading from which register and how many registers to read.

2.5 Error Check Field

The field allows the error check by master and slave devices. Due to electrical noise andother interferences, a group of data may be changed while transmitting from one location to the other. Error Check ensures master or slave devices do not respond to the distorted data during the transmission, which enhances the system security and efficiency. Error Check uses 16-bit Cyclic Redundancy Check (CRC 16).

3. CRC Check

Every message includes an error checking field which is based on the Cyclical Redundancy Check (CRC) method. The CRC field checks the contents of the entire message. It isapplied regardless of any parity check method used for the individual characters of the message. The CRC field is two bytes long, containing a 16-bit binary value. The CRC valueis calculated by the transmitting device, and is appended to the message.

The receiving device recalculates the CRC value during reception of the message, and compares the calculated value to the actual value it received in the CRC field.

An error will be reported if the two values are not equal. CRC calculation is first started by preloading the whole 16-bit register to 1’s. The process begins by applying successive 8-bitbytes of the message to the current contents of the register. Only the eight bits of data ineach character are used for generating the CRC. Start and stop bits, and the parity bit, donot apply to the CRC.

When generating the CRC, each 8-bit character is exclusive ORed with the register 117contents. The result is shifted towards the least signifcant bit (LSB), with a zero filled


65

AcuR

ev 1

300

intothe most signifcant bit (MSB) position. The LSB is extracted and examined, if the LSB equals to 1, the register is exclusive ORed with a preset, fixed value; if the LSB equals to 0, noaction will be taken. This process is repeated until eight shifts have been performed. Afterthe last (eighth) shift, the next 8-bit byte is exclusive ORed with the register’s current value, and the process repeats for eight more shifts as described above. The final contents of the register, after all the bytes of the message have been applied, is the CRC value.
